I've had my zhanchi for a while and noticed that there are scratch marks on the pieces inside. I think these are due to friction. Do I need to get rid of them? Are they slowing my cube down in any way?
This is caused by pieces rubbing against each other. The scratches themeselves do not slow down your cube, however your cube is probably tight which is slowing it down. This is ok. You probably also want to lubricate your cube with some sort of silicone lubricant, such as lubix or traxxas.
